The Diversity and Seasonal Dynamics of Birds at Pingguoshan Park of Kaili

Bird surveys were carried out two to three times per season,and totally nine times,at Pingguoshan Park of Kaili City,Guizhou Province from June 2011 to May 2012.The diversity and seasonal dynamics of the bird in this park was analyzed for better understanding avian information.28 species were recorded,which belonged to 13 families and 3 orders.By comparing the biodiversity index(H′),evenness(J) and dominant index(C) among the four seasons,the results indicated that: the highest index of H′and J were 2.435 and 0.899 in spring,and the highest index of C was 0.158 in autumn,and the lowest index of H′,J and C were in winter.The similarity index of Jaccard of spring-winter avian communities was the highest(0.375),and the Bray-Curtis index of summer-winter avian communities was the highest(0.149).Migration and food are the main factors that affect the composition of avian communities at Pingguoshan Park.
